AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

Raw Attribute Strings

<div my-directive="some string" another-param="another string"></div>

In Rails 3

Data Migrations in Rails Apps

If you need to manipulate existing data when your code is deployed, there are two main ways to do it:

Create a rake task to migrate the data after the code is deployed. This is ideal for more complex data migrations.
Use ActiveRecord models in a migration. This is acceptable for smaller data manipulations.

Regardless of the method you use, make sure to test your migrations before submitting them.

	Rails scaffolding types
	These types are valid since Rails version 2:

	string
	text (long text, up to 64k, often used for text areas)
	datetime
	date
	integer
	binary
	boolean

	// clear canvas
	canvas.clear();

	// add red rectangl
	canvas.add(new fabric.Rect({
	width: 50, height: 50, left: 50, top: 50, fill: 'rgb(255,0,0)'
	}));

	canvas.add(new fabric.Rect({
	width: 50, height: 50, left: 110, top: 50, fill: 'rgb(255,0,0)'
